PHOTOGRAPHI CAMERA-STAND.

TO ALL WHOM IT MAY UONGERN:

Bc it known that I, F. E.`WILKE, of Brooklyn, Kings. county, New York,have invented a new' and improved Photographic Camera-Stand; and I dohereby declare. that the following is' a full, clear, and exactdescription thereof, which will enable others skilled in the art to makeand use the snme,'refcrence being had to the accompanyingfdrawings,forming part of this specification, in which Figure 1 represents avertical longitudinal section of my improved camera-stand, the plane ofsection being indicated by the line :v x, fig. 2.

Figure 2 is a vertical cross-section oi' the same, the plane of sectionbeing indicated by the line y y, iig. 1.

Similar letters of reference indicate corresponding parts.

This invention relates to a new device or support for photographiccameras, which is so constructed that the camera can be raised orlowered and set at any desired angle with the greatest facility andaccuracy.

It consists, first, in the use of a' vertical screw, the head of whichsupports the upper or sliding portion of the support, and which passesthrough a nut that is arranged in the lowor stationary portion of thesupport. By turning 'the screw, the upper` portion can be raised orlowered to any desired height, and with it the camera which reststhereon.

My invention consists, second, in the construction and arrangement ofthe device for setting the camera at an incline. In this a horizontalscrew is swivelled into the sliding-frame, and operates a sliding-nut,by which one or more arms which are hinged to the said sliding-frame,and the free endsvof which rest upon said nuts, are moved, so that theirfree ends are raised and lowered as far as desired. These barsarearranged under the hinged pla-te upon which the camera stands, and thelatter is thus operated as desired.

A represents the stationary frame or support of a camera-stand, made ofwood or other suitable material in the usual manner. On its inside arearranged vertical grooved or other guides B, in which correspondingtongued or other guides C slide, which are part of the sliding-frame D.Ilin the upper part of the frame A i secured u. crossbar, E, in which anut, F, is firmly and stationarily secured. G is a vertical screw, madeof wood or other suitable material, and is swivelled or'hun'g in a.cross-bar, n, of the sliding-frame, and which its through the nut F, asis clearlyshown in the drawings. On the screw G is mounted a pinion, H,which meshes into a. gear-wheel, I, which is mounted on a'. shaft, J, asshown, The latter-has its bearings in the sliding-frame, and is providedwith a crank, b, or other suitable device, whereby it may be easilyrevolved. Thereby the screw G is turned in the nut, and the distancebetween the cross-bars E and t can thus be increased or diminished, orthe sliding-frame A raised or lowered with ease.

It will `be understood, from the following description, that thcsliding-frame rests upon and is supported only by the screw Gr, and asshoulders c c are formed on the screw above and below .the cross-bar a,it is clear that, as the screw is turned, the sliding-frame must beraised or lowered. By the use of 'the screw, .the camera, which standsupon the-sliding-frame, can be accurately adjusted to any desiredheight, whilein thel usual camera stands ratchet-wheels are employed,whereby no very great accuracy of adjustment can be obtained. 0n tcp ofthe. frame D is arranged a horizontal screw, K, which is swivclled tothe same in the manner shown in fig. 1,

and which can be turned by a crankior handle, d. L is aslidingnnt,whichis fitted around the screw K', and

which is guidedbetwecn grooved pieces e e, which are arranged stationaryon the sliding-frame, as is clearly shown in iig. 2, and whichpreventthe said nut from revolving, but not frox'nsliding. M.M are bars, whichare.

pivoted or hinged hear that end of the frame D in which the screw K isswivelled, their pivotingpoints being at about the same height with theVaxis of the screw K. Their free ends rest, upon the nut L, as isclearly'shown Lin iig. 1. N is a plate, which is hinged to the top ofthe frame 'D on that side which is opposite to that 0n i I which thebars M are pivotcd. The free end of this plate rests upon that of thebars M, as shown in iig. 1. It

will be seen that'lby turning the screw K, so that thc nut L is movedtowards the handle of the screw, the free ends of thebars M must beraised, as the nut moves below them towards their pivoting points,increasing their angle of inclination the nearer it approaches thelatter. K The free end of the plate N is thus also raised, and itsinclination increased, and with it that 'of the camera, which standsupon theplate N. By turning the screw ,K in the opposite direction, theuut will move towards 'the hinges of the plate N, and the latter willthus bebrought nearer' to a. level position.

Having thus described my invention, I claim' as' new, and desire tosecure by Letters Patent- 1. The device for raising and lowering thesliding-frameot` a cnmera-sta.nd, which consists of a. vertical 1 screw,G, which is held between theV cross-bends E and a, which are part of thestationary and sliding-frames respectively, said screw being operated bymeans of gear-Wheels H and. I, and bv c handle, b, on a shaft, J, all vns sot forth.

2. The `device for placing the plete N, and the camera which issupported by it, into an inclined position, scid device *consisting ofthe arrangement' und combination with each other of thc screw K,sliding-nut L, pivoted arms M, and hinged plate N, all made andoperating substantially as herein shown and described.

3. The raising and lowering device of a camera-stand, in combinationwith the device for inclining the camera, when the same are madesubstantially as herein shown an described, and when operated by meansof the screws G and K, respectively, as set forth. i WILKE. l
